BAE Systems is aiming a new compact and lightweight head-up display, called Q-HUD, at a wide market that includes light and midsize business jets. BAE claims that the new HUD, introduced at last month’s NBAA Convention, will be 50 percent lighter, significantly less costly and more reliable than conventional HUDs, while also generating less heat and providing pilots with more headroom.
BAE Systems (Booth No. 1881) is aiming its new compact and lightweight head-up display, Q-HUD, at a wide market that includes light jets. BAE claims that the new system is 50 percent lighter, significantly less costly, more reliable, generates less heat, and provides pilots with more headroom, a greater range of view and a range of head motion that is 15 times greater than conventional HUDs.
Until about a year ago, infrared enhanced vision systems (EVS) were exclusively the bailiwick of operators of large aircraft, in which they were installed as upgrades to the standard head-up display. Primarily, the aircraft were the Gulfstream IV/IV-SP/G300/G400, GV/ G500/G550 and Bombardier Global Express, and their EVS add-ons– built by Kollsman of Merrimack, N.Y.
After many years of diligent, and what must often have been discouraging, marketing efforts by their manufacturers, sales of head-up displays (HUD) have now taken off and are climbing rapidly. The main impetus behind this is the recognition by the airlines that HUD confers unique operational and cost benefits that are simply not available in the standard flight deck.
Flight Visions of Sugar Grove, Ill., has started building a mockup of a head-up display overhead projector for evaluations in a Cessna Citation X cockpit. Cessna asked the HUD maker to design the mockup to determine whether the projector fits well enough in the relatively small space available in the Citation X.
MaxVis Inc., a new company established in Portland, Ore., has thrown its hat into the enhanced vision system (EVS) ring, where competition is heating up. EVS units are add-ons to head-up displays (HUD) and use infrared sensors to “see” through cloud and fog to provide an almost photographic quality image on the HUD of the situation ahead, far beyond the pilot’s visual range.
Rockwell Collins will integrate an infrared sensor-based enhanced vision system (EVS) for the Boeing Business Jet and other 737 models using Rockwell Collins Flight Dynamics head-up displays (HUD).
Canada’s CMC Electronics, the former Canadian Marconi, reported it has completed a second set of flight trials of its enhanced vision system, which uses a small infrared camera to capture a real-world view outside and ahead of the airplane and overlay it on a HUD.
Bombardier plans to offer a Rockwell Collins LCD-based head-up guidance system along with its BEVS (Bombardier enhanced-vision system) as an option for the Challenger 605. The package will include the Rockwell Collins HGS-6605 HUD, touted by its manufacturer as offering the “brightest image over the widest field-of-view” of any system on the market.
Ask any copilot of a HUD-equipped airplane what a low-visibility approach looks like, and the answer will be the same–no different from any other airplane. But that’s not because the HUD doesn’t help. It’s because traditionally HUDs have been installed only on the captain’s side, and their optics require the user to be sitting in front of the screen.
